I'm using a 3Com 3CRUSB10075 with r77 of the zd1211 driver on a 2.6.17 
ARM-el kernel (a Linksys NSLU2 running DebianSlug).  It's not working, 
and I'm hoping someone here might be able to shed some light on things.

The zd1211 module loads just fine, and I can scan for APs, and I see my 

> myhost:~# iwlist wlan0 scan
> wlan0     Scan completed :
>           Cell 01 - Address: 00:12:17:C6:D7:C5

>                     Extra:SignalStrength=100%,LinkQuality:92%

>                     Extra:bcn_int=100

But beyond that things don't work.  After doing an 'ifup' (which assigns 
a static address, and sets the ESSID, WEP key and region) I see:

> myhost:~# ifconfig wlan0
> wlan0     Link encap:Ethernet  HWaddr 00:16:E0:03:1F:A5
>           inet addr:  Bcast: 
> Mask: UP BROADCAST MULTICAST  MTU:1500  Metric:1
>           RX packets:0 errors:22 dropped:0 overruns:0 frame:22
>           TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
>           collisions:0 txqueuelen:1000
>           RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

But after waiting a few minutes, the dongle still hasn't associated, and 
seems to have an ever-rising number of 'Tx excessive retries' and a 
few 'Rx invalid frag's:

> myhost:~# iwconfig wlan0
> wlan0     802.11b/g NIC  ESSID:"myessid"
>           Mode:Managed  Frequency=2.432 GHz  Access Point:
> Not-Associated Bit Rate:11 Mb/s
>           Retry:off   RTS thr=2432 B   Fragment thr:off
>           Encryption key:****-****-**   Security mode:open
>           Power Management:off
>           Link Quality=92/100  Signal level=100/100  Noise
> level=0/100 Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:22
> Tx excessive retries:259740  Invalid misc:0   Missed beacon:0

I'm sure the key and ESSID are fine, 'cause I've got two other devices 
talking to my AP with these settings.  Where should I start looking for 
the problem?  What debug can I turn on in order to troubleshoot the 
association?  Is the excessive retries/invalid frag issue the key to 

Thanks in advance for any light shed,
